SPECIFICATION forming part of Letters Patent No. 349,329, dated September 2.1, 1886.

' Application filed July 9, 1886. Serial No. 207,579. (No model.)V

To all whom it may concern:

Beit known that I, Riel-IARD H. WILLET, a citizen of the United States of America, residing at Vashington, in the District of Columbia, have invented certain new and useful Improvementsin Stair-Carpet Fasteners, of which the following is a specification, reference being had therein to the accompanying` drawings.

My invention relates to stair-carpet fasteners.

The object of my invention is the construction of devices which,when properly attached to the stairs, may be readily adjusted in position to securely hold in place the carpet, and in position to allow the carpet to be taken up without detaching the devices from the stairs, thus saving the time, trouble, and injury to the stairs attending the detachment of the devicesnow in use for this purpose.

In the accompanying' drawings, Figure l is a perspective view of one of myimproved devices detached. Fig. 2 is a perspective view of a portion of a carpeted stairway, showing my improved devices attached. Fig. 3 is a front elevation of a portion of a carpeted stairway, showing the positions of the devices adjusted to hold and to release the carpet. Figs. 4 and 5 are longitudinal sections, and Fig. 6 is a side elevation, of the devices, showing inodiiications of construction and attachment or' the springs. Figs. 7 and 8 are plan views of the bearing-surfaces of the presser-plates, showing modilications in their construction. Fig. 9 shows the detached parts of one of my devices.

A designates a bar, provided near its ends with the holes an to receive loosely the fastening-screw and the shank of the presser-plate.

B designates a stud, provided with a base, b, and having a central hole to receive the fastening-screw c, which is extended through the bar and stud and screwed into the riser C of the stairs. The stud is made suflicientlylong to allow the required space forthe movements of the presser-plate between the bar and the stairriser, and the outer bearing-surface of the stud is trued so as to form a true bearing for the under side of the outer end of the bar (or the spring when the spring is constructed to extend over the stud.) rlhe bar A is thus pivotally attached to the stairs, s0 that it may be readily adjustedin the different positions required, as hereinafter fully set forth.

` Ddesignatesapresser-plate rigidlyattached to the inner end of the shank d, which is extended loosely through thehole c in the pivoted bar. rIhe outer end of the presser-plate shank is provided with a pull or knob,f, for operating the device, as herein described.

E designates a spring adapted to force the presser-plate against the carpet and hold it in place on'thc stairs.

lt is evident that the invention does not depend upon any particular construction of the presser-spring. It maybe secured in place by being riveted to the bar, as shown in Fig. 5;

or it may be constructed with the perforated portion 7L extended over the stud, as shown in Fig. 4of the drawings; and instead of a flat 7o spring, as herein set forth, a coil-spring may be placed on the shank between the pivoted bar and the presser-plate, as shown in Fig. 6

of the drawings.

For the purpose of increasing thc holding capacity or' the presser-plates, their bearingsurl'aces are preferably corrugated, as shownin Fig. 8; or they may be provided with points b', as shown in Fig. 7 of the drawings.

This device may be constructed of any suitable material and with any ornamental iinish desired. It is very simple in construction, and not liable to get out of order or to be broken in use, and hence is durable and inexpensive, and,when once properly attached to the stairs, need not be detached, except for purposesother than that of the removal of the carpet.

The devices are preferably attached to the lower portions of the risers ofthe stairs in position for the presser plates to extend slightly within the edges of the carpet and to press and hold the carpet closely and rmly against the risers and against the back portion of the steps, as shown in the drawings.

While I prefer to attach the devices to the risers, as described, they may be attached to the back port-ion of the steps, in which case the presser-plates will have their bearing upon the carpet over the back portion of the steps, close to the lower portion of the risers.

The devices being properly attached to the stairs, as described and shown, and the carpet F being properly secured at its upper end and IOO drawn smoothly and tightly to its place over the steps, the presserplates are drawn back so they will swing clear of the Carpet by pulling on the knobf, and the bar is turned down into 5 position Vt'or the presserplates to bear upon the edges of the carpet, as shown in the drawings.

\Vl1en the carpet is to be taken up, the pivoted bars are turned up, as shown in dotted lines, thus releasing the carpet without dero taehing the devices freni the stairs.

Vhat I claim as new, and desire to secure by Letters Pat-ent, is-

1. A stair-carpet fastener Consisting of a presser plate or foot having a yielding eonnee- I5 tion with an armor aA bar adjustablyattached to a holder adapted to betastened toastairway beyond thelines of the edges of the earpet,where bythe presser plate or i'oot may be adjusted in position to hold in place the earpet, and in position to release the carpet without detaehinzo the deviee l'rorn the stairway, substantially as and i'or the purpose deseribed.

2. In a stair-carpet fastener, the eoinhi nation of the har A, pivoted on the bearingstud B, the presser-plate (j, having the shank d er- 25 tended through a holein the bar, and provided with a. pull, j', and a spring adapted to press the plate upon the carpet, substantially as and for the purposes described.

In testimony whereof I affix my signature in 3o presence of two witnesses.
